The warnings come as firefighters in several communities - including Natick, Millis and Medway - battled brush or other fires over the weekend.

Firefighters from Millis and surrounding communities fought a fire that spread to woods and a garage Sunday afternoon near Larch Road, according to emergency radio broadcasts and social media posts.

On Saturday, Natick firefighters put out a blaze that started in the corner of a Pond Street lot and engulfed a garage. In Medway, firefighters extinguished a half-acre brush fire on Coffee Street within 45 minutes on Saturday afternoon.

Milford firefighters put out a couple small brush fires in the last week and a half, but nothing on Sunday as of 2:15 p.m., Lt. Steve Gies said.

Dry, breezy weather along with tinder and dry leaves on the ground help blazes spread. A lack of greenery on plants also contributes, fire officials said.

"It doesn’t take much (for a fire to get going)," said Natick Deputy Chief Daniel Dow.

The National Weather Service warned of high fire danger in the Bay State on Sunday due to "very warm conditions combined with low humidity, gusty southwest winds and very dry surface fuels."

The danger will likely continue into Monday, the National Weather Service said.

Gies urged people to report signs of smoke to the fire department so firefighters can get on scene as quickly as possible. Spotters in fire towers also keep watch for signs of fires, Gies said.

Natick firefighters prohibited outdoor burning on Sunday based on conditions. Burning is also banned on Monday regardless of conditions because the Boston Marathon will be passing through town, Dow said.

When burning is allowed in town, Dow urged people to have a garden hose ready, never burn construction debris and follow all rules about fires. People should also make sure ashes are completely out, he said.

Fire officials said Saturday's Natick fire started in the back corner of a property at 198 Pond St. around 2 p.m. and spread to a detached garage. Firefighters put out the blaze within about 20 minutes. It destroyed the garage and damaged vinyl siding on the home and a metal shed on a neighboring property.
